The AirTAC GFR600-25MLJC2T AirTAC Filter Regulator NPT1 Low-Pressure is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-25MLJC2T is a filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure steady. This 600-size unit has a 1 in NPT port, a manual drain on the aluminium alloy bowl, the standard 40 um filter element, the low-pressure regulator type, and a round pressure gauge reading in psi fitted. No mounting bracket is included with this code.
It is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with ports from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge styles and scales, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding clamp cylinders on a woodworking or light-metal press that runs at reduced line pressure, where the low-pressure regulator type and the 1 in NPT port suit a high-air-demand circuit.
Conditioning supply air to looms and winding frames: the 40 um element catches pipe scale and corrosion, and the manual drain lets an operator bleed accumulated water at shift start.
Supplying atomizing air to a spray or coating line working at low pressure, with the round psi gauge giving the booth operator a direct readout in the units already used on the line.
Size and port are the first choice: 200 to 600 with ports from 1/8 in to 1 in, this code being a 600 with a 1 in NPT port. Drains come as differential-pressure (default), automatic (A) or manual (M, as here); filter grade is 40 um standard or 5 um with W. An embedded square gauge is standard and an external round gauge optional, in MPa, psi or bar scales - this unit carries a round psi gauge. Threads are PT as standard with G (BSPP) and NPT as order options; brackets are optional. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
The low-pressure regulator type's adjustment range is not published in our sheet, so we confirm it with the datasheet on request. Because flow is published as curves rather than a single rated figure, ask us to check sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes GFR flow as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, downstream demand and this model code, and we will confirm the flow from the datasheet on request.
The M in this code specifies a manual drain: an operator opens the bowl drain to release collected water. The same GFR600 body is also catalogued with automatic (A) or differential-pressure (default) draining - tell us which you need and we will confirm the matching variant.
